The road course at Palm Beach International Raceway was a 2-mile, 10-turn circuit constructed of hot-mix asphalt and set on an aggregate base.

The track was originally named "Palm Beach International Raceway" and was owned by local contractor Joe Bucheck Jr. and his brother Edward.

Another concert featuring Led Zeppelin, Bachman–Turner Overdrive and J. Geils Band was in the works in 1975 but organizers cancelled it when they decided the facility couldn't handle the estimated 50,000 fans that were expected to attend.

In 1996, Moroso considered spending $2 million on a one-mile oval track for stock car racing, but those plans fell through.

Jeremy Clarkson, James May, Richard Hammond and The Stig's American cousin all raced cars at the speedway, that the former three had purchased in Miami earlier.

[13] Once the track gets its FIA Grade 2 certification it will be eligible to host a wide variety of motorsports events including IndyCar Series, Indy Lights, Grand Am and other major forms of racing.

On Saturday, April 23, 2022 a "Last Lap" event was held to commemorate the closure of Palm Beach International Raceway.

[14] The event was announced on Thursday, March 3, 2022 via a web site announcement which stated "Opened in 1964, this iconic venue has hosted championship road races, South Florida’s most prestigious drag racing event, the Citrus Nationals, and some of the largest acts in musical history including the Rolling Stones, Jefferson Starship, and Eric Clapton.

In addition, PBIR has served as a test facility for top IndyCar, sports car and drag racing teams."
